A Dallas police lieutenant who goes by the name “Lucille Baller” when she promotes herself as a recording artist promises to shoot anyone who messes with her in a rap song that was posted on her website.

“Don’t push Ms. Lucy, because you won’t like the consequences,” Lt. Regina Smith raps on the recording. “Mess with me or I will shoot a [expletive], cuz Lucille Baller, she been to hell and back.”

Smith, who oversees burglary and theft detectives at the southwest and northwest patrol investigative units, will probably face an internal affairs investigation over the site promoting her independent record label and music production company, Big Rush In Global Media.

Smith named the independent record label and music production company after her husband, Senior Cpl. Norm Smith, who was fatally shot while he and other gang unit officers were trying to serve a robbery warrant in January 2009.

She removed the rap recording and informed her supervisors about the website on Tuesday after The Dallas Morning News and WFAA-TV asked her for comment. Within hours she was placed on administrative leave.

“I have no comment, and I will deal with whatever happens,” Smith said. “It has nothing to do with the police department.”

Assistant Chief Randy Blankenbaker, Police Chief David Brown’s chief of staff, said the department is “aware of this website and its content, is currently reviewing the issue and will take action consistent with our findings.”

Sam Walker, emeritus professor of criminal justice at the University of Nebraska at Omaha and the author of books on police accountability, found the contents of Smith’s website troubling in light of her profession.

“We all enjoy artistic freedom, but when we have certain jobs, especially jobs as police officers, there’s some limits of what we can say and do,” he said.

On the site, Smith identifies herself as a Dallas police lieutenant. She poses in a black dress with long, flowing red locks and introduces herself as “Ms. Lucille Baller.”

The website shows a photo of Smith and her late husband in their Dallas police uniforms. It states that the recording label was named to honor her husband, who was known to many by the nickname “The Big Russian.”

“Norman was a force to be reckoned with and he bravely went to places where many officers cowered away from,” the site states. “When Norman stepped into any room, everyone took notice of his enormous confidence and presence.”

One of the artists on Smith’s label is Ray Vaughn, a police officer assigned to southwest patrol. Another of her acts is her daughter.

One of the videos posted on the website begins with someone saying, “Dallas police. Dallas police,” followed by gunshots and then a montage of TV footage from her husband’s funeral.

Smith explains on the video that since her husband’s death she has been in a “state of deep remorse and grief.”

“I’ve been alone in my struggle as far as support from the department, but I have not been alone when it comes to friends,” she says on the video.

Sitting at a table with several people, Smith says the music business is quite different from policing.

“You know what I would do to somebody who tried to take advantage of me. You see this bullet right here,” she tells a woman at the table. “I’ll stick it from they rooter to the tooter and bring it out.”

In the next scene, Smith holds a revolver and fires without bullets at a target, explaining that she needs to do so because police officers are required to requalify once a year to carry a weapon.

“I have ‘Ms. Lucy’ right here in my hand,” Smith says, holding the revolver as she spins the empty chamber and then fires the weapon.

The since-removed rap song played with a montage of photos that included Smith in uniform, as well as others of her in skimpy attire and wearing a Lucille Ball-style wig.
